Answer:
3) -1
4) [tex]-\frac{2}{3}[/tex]
Step-by-step explanation:
Taking the cube root of a number is the same as finding what number times itsef three times equals the number under the radical sign.
[tex]\sqrt[3]{-1}[/tex]
[tex]=-1[/tex]
Since (-1) times itself, three times equals (-1).
[tex]\sqrt[3]{-\frac{8}{27}}[/tex]
[tex]=-\frac{2}{3}[/tex]
Since ([tex]-\frac{2}{3}[/tex]) times itself three times equals ([tex]-\frac{2}{3}[/tex]).
